Then you can also fairly say they've killed billions of people - that's the upper end of estimates, could be 1, could be 10, but upper estimate is definitely billions.

Also, please read what I wrote, I meant there is no credible source in this scenario, hence no one should be able to cite anyone's numbers

> Then you can also fairly say they've killed billions of people

No, you can’t. One, it exceeds Iran’s population. Two, no known method of estimation produces a reasonable guess at those levels.

> there is no credible source in this scenario

There are. There aren’t if you assume ex ante they don’t exist, or if you’re committed to ignoring them.
